Proline Promass H 300 Coriolis Flowmeter
Chemically resistant single-tube flowmeter with a compact, easily accessible transmitter. Highly accurate measurement of liquids and gases in applications requiring maximum corrosion resistance.
Field of Application
The highly accurate Promass H is designed for applications requiring maximum corrosion resistance and guarantees optimal safety for chemically aggressive fluids. With its compact transmitter, the Promass H 300 offers high flexibility in operation and system integration.
Key Benefits
- Maximum safety for chemically aggressive fluids with corrosion-resistant wetted parts
- Fewer process measuring points through multivariable measurement (flow, density, temperature)
- Space-saving installation with no inlet/outlet run requirements
- Full access to process and diagnostic information with numerous, freely combinable I/Os and Ethernet
- Reduced complexity and variety through freely configurable I/O functionality
- Integrated verification via Heartbeat Technology
